This invention relates to a paper hanging machine, and it is primarily an object of the invention to provide a machine of this kind that is portable and suiciently light to be easily moved from place to place.

It is also an object of the invention to provide a machine of this kind constructed in a manner to enable the same to be conveniently and electively operated by a single person, and which is entirely manual in its operation.

Another object of the invention is to provide a machine of this kind wherein the paper can be readily placed in such position with respect to a wall to facilitate its application thereto, together with means whereby paste or kindred adhesive material is properly applied to the paper as the same is moved or shifted into position for application.

Another object of the invention is to provide a machine of this kind embodying means for drawing paper from a roll or kindred source into proper position with respect to the wall to which it is to be applied, together with means for initially maintaining the paper out ofcontact with the wall to eliminate hindrance or obstruction to the Working operation.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved machine whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in front elevation of a machine constructed in accordance with an embodiment of my invention, with portions broken away;

Figure 10 is a view in iront elevation of the element illustrated in Figure 9.

As disclosed in the accompanying drawings, B denotes a flat base, preferably rectangular in form, and which has operatively engaged with its corner portions the conventional casters I whereby the base may be readily and conveniently shifted if desired over a surface. The base B, at its front corner portions, has rigidly mounted thereon the upstanding members or posts 2, while the rear corner portions are provided with the upstanding members or posts 3. Each of the members or posts 3 is adapted to have telescopically engaged thereover an elongated tubular member 4 depending from a container 5 having its upper or outer end open. The container 5 is adapted to serve as a receptacle for brushes, hammers and other tools or accessories.

Telescopically engaged over the front members ,A or posts 2 are the lower end portions of the elongated tubular members 6 effectively anchored to the posts or members 2 by the binding screws 1. These members 6 are of a length to extend a material distance above the posts 2 and telescopically engaging from above within the members 2 are the elongated posts 8. These posts 8 are readily shiftable lengthwise with respect to the members 6 in accordance with the relative adjustment desired, 'and such posts 8 are effectively held in selected adjusted position by the binding screws 9 threading through the walls of the-members 6 and having holding or binding engagement with the posts 8. These vbinding screws 9 are preferably closely adjacent to the upper ends of the members 6, as illustrated in Figure l of the drawings.

The posts 8 are of such length as to have their upper end portions at all times above the upper ends of the members 6 and the upper end portions of the posts 8 are received within the tubular members I6 depending from the opposite end portions of a top cross or crown member Il. The posts 8 are securely held within the members i6 by the conventional binding screws I2. The top cross or crown member i, as herein disclosed, is fiat and of material width and at each end portion thereof inwardly of the tubular members I6 but in relatively close proximity thereto the cross orcrown member il' has securely held, as at I4, to its top face the transversely disposed rods I5 extending a required distance fore and aft of the cross or crown member I I. The forward extremities of each of the rods I5 is provided with a depending arm I3 terminating a slight distance below the top or crown member II. The lower extremity of this arm I5 is continued by a rearwardly directed rod I1 in parallelism with the rod I5 thereabove. 'Ihe rear end of this rod I1 is continued by an upstanding arm I8 bridging the space between the adjacent rear ends of the rods I5 and I1, and welded or otherwise rigidly held to the rod I5.

Each of the rods I1 is substantially straight v tubular head I9 and contacting the adjacent portion of the rod I1.

'The lforwardrcorner portions of the base B,

inwardly of the posts 2 and substantially directly n below Athe rod I1, has mounted thereon the guide pulleys 23, and the rearV corner portions of the base B are' provided with theadditional guide pulleys 24 in substantially'transverse alignment with thel pulleys 23; 'c A Disposed over the sheaves 2|- of the pulleys P are the flexible members 25 which pass downwardly from the sheaves -2I and under the pulleys ,'23, .and from the pulleys 23'themembers 25 extend transverselyrof the base B and pass under ythe pulleysl 24 and extend upwardly therefrom to the sheaves 2l. embodiment of my invention one end portionof each of the flexible members 25 is connected,` as at 26, to a bracket 21 rigidly` secured to and depending from an endportion of Ya clamping member 28.` The opposite end portion of thev member 25 extends downwardly through a suit'- ably positioned opening 29 in an end portion of anupper clamping member 3i) and also through an opening'i in the adjacent end portion of the clamping member 28 and suitably secured, as at' 32, to the `bracket* 2S. VVThe flexible members 25,V

in their assembly, are substantially taut but-r suiiciently loose to readily allow for the raising or lowering'of the clamping members 23v and-30.

The clampingV members 28 and 39 are `lat'and coextensive in length and of a length tosubstantially bridge the space between the members 6V or' posts 8, and it is` to-be'noted that the upper clamping member 39 isV freely movable along the exible members 25, while the lower`clamping and 33 and the'weight of the upper member 28 will result in an eifective holding'or clamping of said end portion of the strip S between the members 28 and 39 to allow the strip S to'be pulledv upwardly upon the raising of the clamp',-V

ing members 28 and 3U. f s Mounted upon the base B andv substantially centrally of the field defined by the posts l2 and 3 is a tank T of desiredcapacity. This tank T In thepresent' is of a length materially in excess of the initial width of the paper strip S and is also of considerable width. The end walls 33 of the tank T extend a material distance above the side walls 34 of the tank and the rear upper corners of the end walls 33 are provided with the inwardly disposed brackets 35. Each of these brackets 35 includes an upstanding arm a having a slot 35 opening through the upper or top end of the arm a whereby the bracket provides a bearing support for an end portion of an elongated rod or mandrel 31. This rod or mandrel 31 is of a length substantially equal to the distance between the opposed posts of the upper portions of theend walls 33 of the tank T. The rod or mandrel 31 is adapted to be disposed axially through a roll R of wallpaper whereby the same is initially mounted in desired portion in a manner free for rotation so that the paper strip may be readily withdrawn.

The tankT is adapted to hold a` uent adhe-4 sive such as conventional-paste for paper hanging, as indicated at 38.

The opposed faces of the end walls 33 are a desired distance below the upper or free edges of the side walls 34 has secured thereto the transversely disposed upstanding bearing plates 39. These -plates 39 extend substantially entirely across the tank T and in the present embodiment of the invention each of said plates 39 has its lower marginal portion defined by an outwardly disposed flange 40 welded or otherwise rigidly secured to an end wall 33.

The plates 39, at substantially the transverse center of the 'tank T, are provided with the vertically disposed slots'4l open at their upper. endsr and which slots are of a length to have their inner or closed ends closely adjacent to the bottom margin of the plates 39. These slots 4I receive the extremities of the shaft 42 for the paste roller 43. `As illustrated in Figure '1, this roller 43 is. divided longitudinally into a plurality of sections. sections thereof, are of a relatively ,large diameter so as to extend closely adjacent tothe bottom wall 44 of the tank T.

Each ofthe plates 39, at opposite sides of the slot 4I, is provided in its upper marginal portion with the additional slotsy 45 having their upper ends open. 'I'hese slots 45 are equi-distantly spaced with respect to the slot 4I and have their inner or closed ends terminating above the inner or closed end of the slot 4I. The slots 45 of the plates 39 receive the extremities of the shafts 46 for the guide rolls 41 and 48 arranged, respectively, fore and aft of the paste roller 43. The rolls 41 and 48 are snugly arranged between the depending arms 49 arranged in pairs at the opposite end portions of the guide frame 59. The

arms 49 of each pair are in alignment and spaced apart transversely of the frame. at each vend portion thereof and at its transverse center, is provided with the sliding bolts 5I, each of which engages through an opening52 in the upper portion of the adjacent end wall 33 of the tank T, whereby the frame 50 and the rolls carried thereby are effectively held in applied or assembled position with respect to the paste roll-A er 43. It is to be noted, however, that rthe frameV 50 is readily removable when desired, particularly when initially threading the paper strip S so that the same, as it leaves the roll R, will pass under the roll 48, voverv the paste roller 43, and under the roll 41, as is illustrated in Figure 2V of thei drawings.

'Ihe roller 43, or more particularly theA The frame 5l),v

` The frame 58, or plate as it may also be called, throughout its major length is relatively thick and said thickened portion 53 is provided therethrough with a slot 54. This slot 54 is disposed transversely through the frame or plate 50 and is of a length substantially equal to the width of the paper strip S. Insertible within this slot 54 is a resilient arm 55 of a cutting element E. 'I'his resilient arm 55, as herein disclosed, is integral with and overlies an arm 58 extending along the upper surface -of an elongated cutter head 51 and rigidly secured thereto, as at 58. The arm 55 when disposed through the slot 54 provides means whereby the cutting element E may be readily adjusted to a selected position transversely of the paper strip as it passes over the paste roller 43 and the resiliency of this arm 55 assures the element E being maintainedin such selected position.

When the' element E is applied the cutter head 51 underlies the frame orplate 5U with the arm 56 in close contact with the under face or surface of said head or plate 50. The forward end portion of the head 51 is provided at its transverse center with an open slot 59 in which is received an end portion of an elongated cutter blade 68, said blade being held in position by a pin l extending transversely through the head 51 and through the end portion of the blade within the slot 59. This blade 68 depends from the head 51 and is of a length to closely approach the periphery of the paste roller 43 so that as the strip S passes over the roller 43 it will have a marginal portion properly trimmed, or said strip may be cut in accordance with the width desired. It is believed to be obvious that if desired two of the elements E can be used to trim off both side margins of the strip S, but it is believed, however, unnecessary that such an assembly be illustrated.

The head 51 of the cutting element E has secured, as at 62, to the under surface thereof an end portion of an elongated spring arm B3. This arm 63 extends downwardly and forwardly at a predetermined incline and has direct contact from above with the strip S as it passes over the roller 43 to hold such portion of the strip S smooth while being cut by the blade 68. The outer or free end portion of this arm 53 is slotted, as at Sli, for the passage of the lower extremity of the blade 68.

As illustrated in Figure 2 of the drawings, the bottom wall 38 of the tank T, at opposite sides of its transverse center, is downwardly inclined and at the low point of said bottom wall 38 one of the end walls 33 is provided with a drain opening 65 normally closed by a plug 6B.

The rod or mandrel 31, adjacent to one end, has fixed thereto a surrounding stop washer 61, and the opposite end portion of said rod or mandrel has freely mounted thereon a surrounding washer 58. Encircling the rod or mandrel 31, outwardly of the washer 56, is an expansible coil spring 69, The fixed washer 51 serves to assure the proper placing of the roll R with respect to the paste roller 43 and said applied roll R is maintained in such position by the coaction of the spring pressed washer 68 therewith. As is clearly illustrated in Figure 3, this coacts with the washer 68 and the upstanding arm a of the adjacent bracket 35. In applying a paper strip to a wall the clamping members 28 and 38 are at substantially their lowermost positions or closely adjacent to the tank T. The free end portion of the strip is then engaged between the clamping members 28 and 30 with a portion 18 extended. The clamping members 28 and 38 are then raised or moved upwardly to the desired height, and during which operation the strip S is pulled from the roll R and over the paste roller 43, resulting in the proper transfer of the paste within the tank T to the attaching surface of the strip S. In the first operation paste will have to be manually applied to the free end portion of the strip but thereafter this will be unnecessary. It is also believed to be obvious that in applying the paper to a wall the machine in its entirety is brought into close proximity to such wall so that the extended portion 18 may be adhesively attached to the wall. After this operation the clamping members 28 and 30 are moved downwardly so that the pressure roll 1l rotatably carried by the upper clamping member 38 will force the strip against the wall to' complete the operation.

Connected, as at 12, to the under surface of the lower or fixed clamping member 28, at points spaced longitudinally thereof, are the upper extremities of the elongated depending flexible members 13. These members 13, at points spaced lengthwise thereof, are connected, as at 14, to the transversely disposed bars 15. Each of these bars 15 is provided at its ends with the eye members 16 through which the flexible members 25 freely pass. When the clamping members 28 and 30 with the attached strip S are raised or elevated these cross bars 15 provide means to prevent undue sagging of the strip S below the clamping members 28 and 30, and particularly to prevent the strip S below said clamping members 28 and 38 having contact with the wall to which the strip is to be attached.

It is to be pointed out that as the clamping members 28 and 38 are moved downwardly the upper member 38 will readily move suiciently away from the lower member 28 to allow for the free passage along the paper strip S therebetween and when the clamping members 28, or more particularly the pressure roller 1l, has been brought down as far as desired the paper strip may be readily cut off by pressing the same upon the upstanding cutting blade 11 secured to the forward edge of the base B and extending a desired distance thereabove Resting upon the base B between the members 6 and between the cutting blade 11 and the tank T is a drip pan 18 of a length to receive and support upon its end walls the bars 15 as they are lowered so as to catch any paste which may drip during the working operation. It is to be stated that this pan 18 is free of connection with the base B so that it can be easily removed and cleaned.

'I'he clamping member 38 swings inwardly and its attachment to the flexible members 25 is such that it is readily removable. When the paper strip S is inserted between the members 28 and 39, there is a material length of paper which hangs over these members. As there is paste on one side of the paper strip S, it is difficult for such strip to slip back and, furthermore, the greater the tendency of the strip S to slip, the tighter becomes the member 38.

When the paper strip S is attached to the wall and the clamping members 28 and 38 start to go downward, the clamping member 38 opens and allows the clamping members to descend with the member 28 on the inside of the paper strip and the member 38 on the outside of the paper strip S.

Connected, as at 12, to the under surface of the lower or xed clamping member 28, as' hereinbefore described, at points spacedk longitudinally thereof, are the upper extremities of the elongated depending flexible members 13. These members 13 at points spaced lengthwise thereof are connected, as at 14, to the transversely disposed bars 15, each provided at its extremities with the eye members 16 through which the flexible members 25 freely pass.

When the clamping members 28 and 30 with the attached paper strip S are raised, these cross by the coiled spring 69. There is no drag of the arm 63 because this arm bears no Weight on the paper strip S although it does hold the paper strip S smooth and the blade 60 in place Without pressing down on the paper strip S.

It is also to be explained that in papering Y a`room, in instances where'the machine cannot bars 15 provide means-to prevent-undersaggingV of the-paper strip S below the clamping members 28 and 3) and particularly to preventthe strip S below` said clamping members 28r and 3B having contact'with the Wall to which the strip is to be attached. This results in the bars 1E carrying or bearing the weight of the paper strip S, thus relieving the clamping members 28 and 30 of the Weight of the paper strip. As the paper strip is raised or elevated,V the bars 15 and flexible member 'I3 fall in place at spaced distances from each other and cling to the adhesive side of the paper strip S and thus assures the softest and cheapest paper to be hung Without breaking or falling apart of the paper.

The washer 6l and the coiled spring 69 simply assure the proper placing of the roll R. The coiled spring 69 is not of suicient strength to impose enough pressure on the ends of the roll R to stop the paper from rolling off freely but will hold the roll R from moving out of place. There is nothing to prevent the mandrel or rod 31 from revolving in its sockets. There is, therefore, no vfriction produced by the Washer 61 or get suiciently close to the wall, such as around a sink or other obstruction, the paper strip S may be rolled off and cut-at the desired length and width, taken from the machine by the operator and placed Where it should go.

From the foregoing description it is thought to be obvious that a paper hanging machine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility With Which it may be assembled and operated. y

I claim:

A paper hanging apparatus comprising a portable base, a paste tank on the base, a plate, means for mounting the plate over the top portion of the tank above the paste roller, a paste roller mounted within the tank below the applied plate, guide rolls carried by the plate and positioned fore and aft of the paste roller, a strip of paper being adapted to pass under the guide rolls and over the paste roller, said plate and guide rolls being applied or removed as a unit, a paper cutting element carried by the plate, and means carried by the cutting element for contact with the paper strip as it passes over the paste roller to cause the paper strip to smoothly ride over the paste roller.
